Blazon: Or a gonfanon gules; on top of the shield two arms in saltire proper, clad in puffed sleeves gules slashed or, each holding an antler sable
The source of the gonfanon is the arms of the principal branch of the Counts Palatine of Tübingen, who were based in the area in the early twelfth century. I don’t generally make a practice of describing shield ornamentations that don’t fall into the standard crest/supporters/mantling format, but these do appear to be explicitly part of the official blazon. They were evidently granted by Duke Ulrich of Württemberg (hence the antlers) for the town’s loyalty during the Poor Conrad uprising.

Both coats quartered here were used by the de Bermingham family at various points in time. The family also quartered the coats, but in opposite quarters; the city changed the order for difference. The city was previously granted arms in 1889, which used a fess ermine instead of a cross, and a mural crown instead of a mitre. The supporters in the previous arms were also reversed, with Industry on the dexter and Art on the sinister.
